Kristen Stewart arrived in Cannes for the annual star-studded film festival doing what she does best: defying styling rules. On Monday, the Oscar-nominated actress was seen leaving the Hôtel Martinez in the French city in a cute-but-casual look that has rightfully earned a place on our summer mood board.

Even when Stewart is dressing down, she's still wearing Chanel, of course. The actress wore a graphic T-shirt designed by the brand with slouchy, cut-off denim shorts that revealed the band of her high-waisted boxers underneath. Shin-length white socks and black boots accompanied the look, which she accessorized with matching sunglasses and a silver chain necklace. Later, she added an olive-green bomber jacket. Her blonde hair was worn in a deep side part and styled in effortless beach waves.

The star is promoting her upcoming movie Crimes of the Future, set to be released in June. According to IMDb, the sci-fi horror film, directed by David Cronenberg, will follow the human race undergoing a transformation in the process of adapting to a new synthetic environment.

"I guess that is the description of this movie: it's going to either attract or repel people," Cronenberg recently told Deadline. "Basically, I'm returning to a kind of filmmaking that I haven't done for a while. And the feeling is that there's a new audience for a film like Crimes of the Future that didn't exist when I was making my last three or four films. So, it's my return to the flesh."
